Filed: 1976-03-16
Abstract: 1488788 Animal husbandry G GUIBERT 16 March 1976 [17 March 1975] 10570/76 Heading AIM A sand bath for chinchillas is provided by a cylindrical container b holding sand and pivotally mounted about a horizontal axis substantially in the plane of a wall of the cage j. The container has an internal partition d, e extending chordally across the container from an edge of a longitudinal opening c, part d of the partition adjacent the open ing being imperforate and the remaining part e being perforated. In use, sand is put into the compartment lying beneath the opening and the container is rotated by a crank i geared to the container so as to bring the opening within the cage to provide access to the animal. When the sand is soiled by excreta, the container is rotated anti-clockwise (as viewed in the drawing) to bring the sand-filled compartment uppermost, whereupon the sand passes through the perforations in the partition, leaving the excreta behind. Continued rotation of the container brings the opening to its lowermost position outside the cage and the excreta falls out, the imperforate part of the partition retaining the sand. The container can then be rotated clockwise until the sand re-enters the original compartment. To change the sand, the container is rotated further clockwise until the opening c is downwardly directed to discharge the sand. The crank i may be geared to a plurality of containers serving a plurality of aligned cages.

Title: Improvements in bomb crates and release mechanism for aircraft
IPC: B64D1/04
Filed: 1925-04-25
Abstract: 314,666. Roe, E. A. V., and Roe & Co., Ltd., A. V. April 25, 1925. Dropping bombs from aircraft.- A horizontal bar b, Figs. 1 and 2, for supporting a bomb a in a crate containing several such bombs and supporting bars is pivoted at one end and held up at the other end by a pair of catches c, c pivofed at d, d and urged to the engaging position by springs. A vertical slide f has flanges which normally confine rollers e, e on the catches, thereby locking them in their engaging position. A bomb is released by a downward movement of the slide f, which brings gaps in its flanges opposite the rollers e, e and at the same time forces a wedge g between the catches to move them away from the bar b. The slide f is operated in steps by lugs q on a disc p, and is locked at each step by a pawl n which is temporarily lifted by fingers o on the disc p to permit each operation. One slide f controls the release of all the bombs vertically superposed; and all the discs p for the several slides f are mounted on the same transverse shaft and connected by chain gearing to a cam t, which a spring tends to turn in the direction indicated by the arrow, but is normally locked by a pawl u. This pawl can be pulled from a distance by a trigger 6. It then releases the cam t and at the same time releases another pawl v which is put in action by a spring, whereby the cam is stopped again after the lowest bombs have been dropped. If a trigger 7 is first pulled, it locks the pawl v out of action, so that when the trigger 6 is pulled the cam t is free to turn to release several sets of bombs in succession. The trigger 6 can be locked by a safety member 5. The loops 8, Fig. 5, of the safety members of the fuzes of the bombs may be engaged by bolts 10, all operated simultaneously. When the loops are thus engaged, the safety members are pulled out and the bombs thereby armed when the bombs are dropped; when the bolts are out of engagement, the bombs can be dropped unarmed, as may be required when making a forced landing.

IPC: B27K5/04
Filed: 1932-04-18
Abstract: 394,112. Drying systems. GONTIER, L., 14, Rue Portalis, and ROUGI•, M., 108, Rue de Ranelagh, both in Paris. April 18, 1932, No. 11035. Convention date, April 17, 1931. [Class 34 (ii).] Wood, impregnated articles, plaster, cement, or other materials are dried by enclosing the article or material in a closed drying oven 1, applying heat thereto, vaporizing the moisture or liquid therefrom at ebullition point under reduced pressure, passing the vapour formed through a pipe cycle 3 in which is disposed a fan 4 and a heater 5, and returning the heated vapour to the autoclave to maintain the heat of the article or material therein. The article or material is thus dried in the presence of the vapour of the liquid to be removed therefrom, which may be water in the case of damp materials such as wood, shavings, powders, or the like, or may consist of alcohol, spirit, or white spirits when drying electrical coils after impregnation. A branch pipe is connected with the pipe cycle 2, containing a condenser 6 and a vacuum pump 7 for the purpose of aspirating the vapours to the atmosphere. At the beginning of the operation, the air contained in the system may be driven out by introducing thereinto at a nozzle 8, at approximately atmospheric pressure, vapour of the same composition as the liquid to be extracted, the exclusion of the air being assisted, if necessary, by the vacuum pump 7, so that the drying is effected without risk of oxidation. The vapour to be circulated may also be obtained initially from the articles or materials to be dried, by sufficiently reducing the pressure. At the end of the drying operation, when the article or material contains sufficient heat to vaporize all the remaining moisture under sufficiently reduced pressure, the fan 4 is stopped, and the drying completed under the highest vacuum attainable with the aid of the vacuum pump 7. In drying linen, the temperature of the circulated vapour should not exceed 75‹ C., while for drying wood or the like, the temperature may be 90-100‹ C.
